LOOM FOR WEAVING CHENILLE OR FUR PILE FABRBCS.

SPECIFICATION forming part of Letters Patent No. 324,287, dated August11,1885.

Application tiled February 0, 1883.

To all whom it may concern:

Be it known that I, WILLIAM ADAM, (of the firm of 'Iomkinson 8L Adam,) asubject of the Queen of Great Britain, residing at Kid derminster, inthe county of Worcester, England, have invented certain new and usefulImprovements inv Looms fOr'VVeaving Chenille or Fur Pile Fabrics, (forwhich I have received Letters Patent in Great Britain, No. 3,087, datedth June, 1882,) of which the following is a specification.

My present invention has for its object improvements on an invention forwhichUnited States Letters Patent were granted to me dated August 22,1882, No. 263,085, and relates, rst, to means for insuring the chenilleor fur pile being brought up into its proper position. For this purposeI so construct the cam giving the rising and falling motions to the reedas that in the working of the loom eXtra falling and rising` motionsshall be imparted to the reed, so as to cause the same to strike thechenille or fur last inserted a second time with the inclined upper endsof the dents, the reed afterward rising in its backward motion to enablethe shuttle to go across-the loom.

According to the second part of my invention I employ a fixed guide-reedplaced as close as possible to the track of the catcher warp needles, inorder to steady the groundwarp threads, and thereby insure the saidneedles entering their proper spaces between the ground-warp threads.

According to the third part of my invention I so construct the camgiving thel rising and falling motions to the catcher-warp needles thatthe full downward traverse of the said needles is divided into threeseparate falls, in order to. facilitate the setting and holding of thechenille or fur pile as it is being brought into its proper position.

According to the fourth part of my invention, when it is required toinsertan eXtra or a floating warp, I employ, as heretofore, an extrashaft or leaf of healds, but instead of operating such eXtra shaft orleaf in theA manner heretofore adopted, I operate it by means of theother leaves or shafts, or by some of them, according as it is requiredto raise such extra shaft or leaf at the rise of every heald or at therise of only certain of them. This I effect (No model.) Patented inEngland June 30, 1882, No. 3,037.

by mounting at the top of such extra shaft or leaf one or moreprojections capable of being fixed in position by screw or otherwise, soas v to extend over some or all of the other shafts or leaves, or overprojections therefrom, and

thereby cause such extra shaft or leaf to be raised at the rise of everyshaft or leaf, or at the rise of only some of them.

And in order that my said invention may lbe more clearly understood andreadily carried into effect, I will proceed, aided by the accompanyingdrawings, more fully to describe the same.

In the drawings, Figure 1 is a cross section,

-and Fig. 2 is a sectional side view, of parts of a loom for weavingchenille or fur pile fabrics,

showing my present improvements applied thereto. Figs. 3 and 4: arerespectively a vcross-section and a horizontal section of partsparticularly the cams for operating the lathe and the healds with theirconnections.

In all the figures like parts are marked with similar letters ofreference.

' In the said drawings, my improvements are shown as applied to such aloom as is represented in my said previous Fatent,No. 263,085, it beingunderstood that the chenille or fur is inserted inthe open shed (formedby the ground-warps and thecatcher-warps) by means of a finger ortraverser, which carries the said chenille or fur through that shed fromone side of the loom to the other.

a is the main framing.' b is the first-motion shaft. c is the cam ortapped shaft. d d are the lathesw'ords. e is the reed. ff are thecatcher-warp needles. g g g are the shafts or leaves of healds which areoperated in the usual way, andrh is an extra shaft or leaf of healdsoperated in manner hereinafter dcscribed. V

The reed e is operated, as described in the specification of the LettersPatent hereinbefore referred to,and as shown herein at Fig. 1,

by cams e', which, by levers ci and connect.

ing-links e3, give a downward motion to the reed e, while springs e4give the upward mo- IOO tion thereto. According to such former pat cnt,however', only one fall and one rise were given to the reed at eachrevolution of the cam e-tl1at is to say, for each insertion of chenilleor fur but according to the first part of my present invention I soconstruct the cam e' that it shall impart two falls and two rises to thereed c at each revolution of the said cam. This construction is shown inFig. l of the drawings, where the cam c' is represented as beingprovided with two falling grades, s' S2, and with two rising grades, I.t, which grades operate upon the truck of the lever ei in the manner inwhich cams usually act upon their levers. By constructing the cam c asshown in the drawings I cause the reed e, as described in my said formerspecilication, iirst,to strike the last-inserted chenille or fur withthe inclined faces of the upper ends, cii, of the reed e, (that is, whendown.) and then to rise so as to stroke np the chenille or fur pile. Thereed e retires from the fell of the work in this position, and then inagain coming forward it is caused, according to my present invention, tofall, and again to strike the chenille or fur pile with the upper ends,0*, after which it again rises as it recedes, to enable the shuttle torun across the loom. The reed e then falls and again strikes the workwhen down, after which it remains down, while the lathe goes back torest, in which position of such parts-that is,when the lathe is back andthe reed down-the fur or chenille is carried across the loom. By thuscausing the reed to strike the chenille twice the portions of the furpile which have not been struck up by the first blow of the reed areacted upon by the second blow thereof, and consequently the fur pile isstruck up with much greater uniformity than is practicable when it isoperated upon but once by the reed.

The means which I prefer to use to operate the lathe when the reed ismoved, as above described, are represented more particularly in Figs. 5and (5. Each sword d of the lathe is connected by means of atoggle-link, d, with an arm, d, which is fitted to vibrate freely uponthe first motion-shaft b. Each of these links d is operated by a cam, d,secured to the camshaft c, the cam operating upon the link through theintervention of the truck (1*, lever d, and rod d6, which last is, bypreference, made adjustable, as represented in said drawings. The gradesdi of the lathecams d are constructed, as represented in said Fig. 6, soas to raise and depress the respective toggle-links d, and thus move thelathe forward and backward. As the cam-grades d occupy only a part ofthe periphery of the lathe'cams d, thelathe remains at rest during apart of each revolution of the cams-that is, alter the last cam-grade inthe series has operated until the first camgrade is brought around tothe lever-truck d.

According to the second part of my present invention I employ a fixedguide-reed, t', as shown, placed as close as possible to the track ofthe catchcr-warp needles f f, and of the same gage as the latter inorder to steady the ground-warps, and thereby insure the said needlesentering their proper spaces between the ground-warp threads.

According to the third part of my present invention I divide the fulldownward traverse of the catcher warp needles j f into three separatefalls and dwells, in order to facilitate the setting and holding of thechenille or fur as it is being brought into its proper position. Forthis purpose I employ, as described in my said former specification andas shown in the accompanying drawings, a cam, here lettered j", which,by a lever, f2, connecting-rod f", and lever f gives the rising andihlling motions to the catcher-warp needles f f but instead of givingmerely one rising and two falling motions to such catcher-warp needlesff in the full extent of their traverse, I construct the cam f, as shownat Fig. 2, with three grades, so as to divide the full downward traverseof the catcher-warp needles ff into three separate falls, the first ofwhich is determined by the grade 1*, and carries the catcher-warpneedles ff down to the posi tion marked l, Fig. SAthat is, sufficientlyfar to enable the catcherwarps to hohl the chenille or fur and to remainin such position while the latter is being adjusted, and yet permit theweaver readily to draw the selvagethread from under and beyond, so as toplace it outside the chenille or fur when the latter is turned at'theselvage. The second fall is determined by the cam-grade 2*, and carriesthe catcher-warp needles f f down to the position marked 2, Fig. S-thatis, sufficiently far for the catcher-warps to securely hold the chenilleor fur in its adjusted position-in which position the catcher-warpneedles ff remain while the chenille or fur is being beaten and strokedup. The third fall is determined by the cam-grade 3*, Fig. 3, andcarries the catcher-warp needles ff down to the position `marked 3 inFig. S-that is, to the bottom of the shed-where they remain sufficientlylong to enable the shuttle to be thrown across the loom the requirednumber of times to bind the catcher-warps, and consequently the chenilleor fur. They then again rise and return to the position marked 0, wherethey remain while the chenille or fur is being carried across the loom.

According tothe fourth part of my present invention,when it is requiredto insert an extra 01 a floating warp I employ, as heretofore, an extrashaft or leaf, 7L, of healds; but instead of operating such extra shaftor leaf h in the manner heretofore adopted I operate it by means of theother leaves or shafts g g g, or by some of them, according as it isrequired to raise such extra shaft or leafh at the rise of every heald gg g, or at the rise of only certain. of them. rlhis I effect by fittingthe upper bar of such extra shaft or leaf lo with one or moreprojections or studs, h, Fig. 3, capablc of being f1xed 1n position byscrew or oth.w

IOO

IIO

erwise, so as to extend over some or all of the other shafts or leaves gg Lf/,or over projections therefrom, and thereby cause such eXtra leafor shaft h to be raised at the rise of every shaft or leafgg g, or atthe rise of only some of them. The Ymeans by which I prefer to operatethe said leaves or shafts g are represented more particularlyinFigs. 5and 7 ofthe drawings, each leaf g being operated by anappropriate cani,g', through the intervention ofa truck, g2, lever g3, rod g4, andoverhead lever g5, from the inner end of the last of which the leaf issuspended. The cams g', two of which are shown in the drawings, aresecured to. the cam-shaft c. I have used and have described cams foroperating the reed, the catcher-warp needles, and the shafts of thegroundwarp threads, but equivalents for these may be used for the samepurpose.

I-Iaving thus described the nature of my said invention, and the mode inwhich I carry the same into effect, I would have it understood that whatI claim is- 1. The combination, substantially as before set forth, ofthe reed of the loom with cams constructed with two falling grades andtwo rising grades, whereby two falls and two rises are imparted to thereed for each insertion of the chenille.

2. The combination, substantially as before set forth, of the cams e,constructed and operating as described, with the levers e2,connecting-links e3, springs e4 c, and reed e.

3. The combination, substantially as before set forth, of thecatchenwarp needles with the guide-reed, which is set close to the trackof said needles so as to steady the ground-warp threads and insure theentrance of said needles in the spaces between said ground-Warp threads.

4. The combination, substantially as before set forth, of thecatcher-warp needles with a cam constructed with three grades, wherebythe descent of the said needles is divided into three falls,substantiallyas described.

5. The combination, substantially as before set forth, of the cam f',constructed with three cam-grades, the lever f2, connecting-rod f3,lever f4, and catcher-warp needles f f.

6. In combination with the leaves or shafts g g g of healds, the eXtraleaf or shaft h, and projection or projections h, extending over andoperated by some or all of the leaves or shafts g g g or by projectionstherefrom, substantially as herein shown and described, and for thepurpose stated. v v
